A British television channel is broadcasting a new documentary on Princess Diana using controversial videotapes in which she candidly discussed her marital problems and her strained relationship with the royal family.

The recordings of Diana speaking to her public speaking coach, Peter Settelen, in the early 1990s included her description of how Queen Elizabeth II reacted when she asked the monarch for advice about her failing marriage with Prince Charles.

"So I went to the top lady, sobbing. And I said 'What do I do? I'm coming to you, what do I do?' And she said 'I don't know what you should do,'" Diana said. "And that was it. And that was help."

This year marks the 20th anniversary of Diana's death in a Paris car crash on Aug. 31, 1997, which was followed by an outpouring of grief in Britain and beyond.

Diana and Charles married in 1981 and divorced in 1996 after having two sons, Prince William and Prince Harry. The tapes include her discussing Charles' relationship with Camilla Parker Bowles, whom Charles later married in 2005.

The recordings also show Diana talking about falling "deeply in love" with a man widely believed to be her protection officer, Barry Mannakee, as well as Charles' attempts to woo her during a barbeque in 1979 when she was 18.

Police held some of the videotapes after they were seized in ex-royal butler Paul Burrell's home in 2001. Diana's family tried to make a legal claim to the recordings, but they were returned to Settelen in 2004.
